Abstract

A brush for tooth and personal hygiene comprises a bristle carrier and bristle bundles fixed thereto, the ends of the bristles being located in at least two different planes perpendicular to the bristle extension. The cleaning action is improved in that over a bristle carrier surface of max 6 mm2 are provided at least two bristle bundles and that either the ends of the bristles of a single bundle or the ends of the bristles of adjacent bundles are located in at least two different planes.

Description

Tooth brush for health protection

The present invention relates to tooth brush for health protection, comprise brush carrier and the pieces that is fixed on the brush carrier, bristle ends is arranged at least two the different planes vertical with the bristle lengths direction.

The deciding factor of toothbrush validity has many, comprises the pure physical dimension of the area and so on of bristle diameter, bristle lengths and hair brush area; Strength characteristics of bristle density, bristle material, crooking ability and reset capability and so on and the bristle layout on carrier.

People recognize, fully the straight enveloping surface that also promptly forms of straight working face by bristle ends can't brush clear tooth, particularly at the slot place, because bristle is all shown same direction greatly when brushing teeth, promptly opposite with toothbrush moving direction direction is crooked and can't stretch in the slot.Similar problem also appears at the neck place that carries out the transition to gums.Another problem is, the outer surface of the tooth in the nipper district is outer convex surface and its inner surface is inner sunken face, therefore can't brush the inner surface of clear nipper especially.

The outer surface of single tooth and the curvature of inner surface are also inequality, and is last, and in tooth district, back, the inside and outside morsal shape of tooth is also different.With straight working face and bristle inlay very closely above-mentioned toothbrush brush not the main cause of clean tooth be that bristle connects mutually, as a result bristle with the side of brushing teeth bending in the opposite direction, working face can't all be fitted with various tooth contours.

For overcoming this problem, there is the people that the toothbrush pieces is made different length and/or different angle positions.Therefore there is people's (United States Patent (USP) 4010509) to do the pieces at brush carrier longitudinal middle part place shortlyer also at angle than both sides edge.But the bending identical with above-mentioned toothbrush still can take place in the bristle of each pieces.Bristle with same length is still promptly crooked in the opposite direction with the side of brushing teeth with a direction.

The situation of another kind of existing toothbrush (United States Patent (USP) 3722020) is similar therewith, and wherein, the pieces end is arranged in three working faces, its height from the middle part outside portion increase successively.Its objective is the roughly working face of indent of acquisition one, so that brush the outer surface of the tooth in the clear nipper district.

In another kind of existing structure (United States Patent (USP) 4979782), the length of the bristle in the same pieces is different and form the working face of a convex or concave and the length of different pieces can have two kinds of length, and promptly the pieces of toothbrush front portion is than back minister.In another kind of toothbrush (EP449655), pieces does not on the same group have different pieces diameters and different length, and the acting surface of bristle ends is arranged in two different planes, vertical approximate vertical of these two planes and brush carrier.When being positioned at regard to the direction of brushing teeth than the undercoat bundle when becoming mildewed Shu Shangyou, they must work on the direction of brushing teeth.The bundle that becomes mildewed of bending will neutralize them against them when brushing teeth in the opposite direction.

Bristle in the last same pieces of handlebar is made (EP473312) of different length.But this patent is just opened up not open pieces in order to increase thick bristle ends, and if increasing thick portion is arranged in a plane, pieces must be opened up not open.This moment, thereby bristle still can connect whole pieces bending when brushing teeth mutually by increasing thick portion.

Since in the toothbrush density of bristle greatly thereby bristle must be superfine, therefore in all existing structures of single pieces, the connecting mutually of bristle makes brushes teeth and can't get out of the way mutually.

Even change method for brushing teeth according to dentist's suggestion, for example to brush teeth or cause vibration with the Mechanical Driven toothbrush from gums towards tooth, above-mentioned situation can not change to some extent yet.In fact, dentistry studies show that, toothbrushing force is too high to have caused coming off of gum top layer and dental enamel, and if make bristle reach inaccessible position and firmly brush teeth, toothbrushing force must be too high.

In the toothbrush of structure with first section proposition, the objective of the invention is to propose a kind of structure, it can make fit the most curved surface of tooth of the acting surface of pieces, and with use which kind of method for brushing teeth irrelevant.

According to the present invention, this purpose realizes like this, at 6mm at the most ²The brush carrier surface on arrange at least two bundle bristles, and the end of the end of the bristle in the same pieces or the bristle of adjacent pieces is arranged at least two Different Plane.

Because at 6mm at the most ²Surface area in cloth lid at least two bundle bristles, thereby can reduce the acting surface that each pieces end forms.Therefore, total working face of bristle is subdivided into has the long-pending many pieces of minimal surface, but bristle is still arranged intensively.Add other measure of the present invention, also promptly use the bristle ends in the pieces or the bristle ends of adjacent pieces to be arranged at least two Different Plane, just can be divided into very little acting surface to the profile of working face with different aspects, thereby they have the different degree of depth that stretches on the flank of tooth, and reduce connecting mutually of bristle, thereby can be better and the tooth application of a surface, also promptly make than short bristles and more work than easier the getting out of the way of long brush hairs.

In a preferred embodiment, the end of the bristle in the bristle ends in the same pieces or three the adjacent pieces is arranged in three Different Plane.

Bristle ends in the same pieces can be arranged in some concentric planes, and in addition, each plane of some pieces of same level can be stretched or along the extending transversely of brush carrier along brush carrier.The direction of these planes on brush carrier is vertical can change.

According to another embodiment, the bristle that the end is arranged in same plane has identical diameter, and that the end is arranged in the diameter of bristle of Different Plane is different.Like this, the end be arranged in an acting in conjunction face bristle rigidity can be arranged in the bristle on another plane different with the end.

At last, the end is arranged in the characteristic of the bristle on same plane, for example material, surface area, color or the like can be arranged in the bristle on another plane different with the end.

Below in conjunction with non-limiting example and accompanying drawing in detail the present invention is described in detail.In the accompanying drawing:

Fig. 7 represents the physical dimension of the local hair brush area of a toothbrush.

At first referring to Fig. 7, this illustrates the details of a brush carrier that studs with bristle.At 36mm ²Surface area on be furnished with the pieces of 25 beam diameter 0.6mm, the spacing between each pieces is 0.6mm, thus at about 6mm ²Surface area on have 4 the bundle pieces.The most modern manufacturing process manufacturing of the most suitable usefulness of this layout.

Fig. 1 a represents the details with a toothbrush of existing bristle of having of this technology manufacturing or pieces structure.It comprises a brush carrier 1 and the pieces 2 that is made of some bristles 3.The length of pieces 2 is all identical, thereby their end is arranged in the straight enveloping surface of a formation working face 4.

Fig. 1 b illustrates the tooth in the nipper district, comprises nipper 5 and is connected to the back of first on nipper tooth 6.The end of pieces 2 is with crooked in the opposite direction with the side of brushing teeth when brushing teeth, and this can find out from leftmost pieces 2.Middle pieces launches, but much effects are not played in its end, and rightmost pieces does not work.Can see that especially bristle or does not only partly stretch into slot.

Fig. 2 a illustrates the present invention's one toothbrush, and wherein, pieces 2 is fixed on the brush carrier 1 with layout shown in Figure 7.The length difference of each bristle 3 in same pieces 2 or the bristle pack, thus their end is arranged in three stairstepping acting

surfaces

10,11 and 12 in the embodiment shown.

In Fig. 2 b, the toothbrush that Fig. 2 a is shown is positioned at when brushing teeth on the exterior of teeth on one of standard use location.Still can see the nipper 5 and the first back tooth 6.Comparison diagram 1b and 2b can know and find out that when the face of brushing teeth pressed down bristle, bristle got out of the way with various different modes.Although the pieces on the left side fully toward a direction (with the side of brushing teeth in the opposite direction) bend and open, but because the stairstepping acting surface of this each bristle of pieces is against the positive camber of tooth, therefore the bristle of other pieces is all stepped down with different directions, thereby still have the part bristle to stretch into slot fully, and the bristle action of other bristle of same pieces or adjacent pieces is on the flank of tooth.Can see that from Fig. 2 c situation is also so multiple when brushing teeth the tooth inner surface.The bristle curved surface of tooth of being brushed teeth of can fitting best comprises slot.Shown in Fig. 2 d, also can obtain best the applying on the face chewing.

In the embodiment of Fig. 3 a, each pieces 2 comprises that its end is positioned at the middle part bristle 11 on the acting surface and is positioned at bristle 11 both sides, its end and is positioned at

bristle pack

13 and 14 on the same-

action face

11,10 neither.The effect of this structure can be found out from Fig. 3 b.

Fig. 4 a illustrates a branch of pieces 2 in Fig. 1 a toothbrush.This length of bristle 3 that is roughly circular pieces 2 is all identical.

Fig. 4 b illustrates a branch of pieces 2 of the embodiment 4 of Fig. 2 a-2d.The end of the bristle of this pieces 2 is positioned on the plane that with this pieces length traversed by three are mutually ladder.On the longest a part of bristle 17 sides is a part of bristle 18 of middle length, is the shortest a part of bristle 19 then.Fig. 4 c illustrates, the stairstepping acting surface of the bristle in the circular pieces 20, the middle long brush hairs 22 in promptly outer field short bristles 21, middle level and the long brush hairs 23 of internal layer.

In Fig. 4 d embodiment, the layout of a pieces 2 is opposite, so bristle 25 length of internal layer are the shortest, and its concentric middle level is middle long brush hairs 26, outer is long brush hairs 27.

In layout shown in Figure 7, also can be that the acting surface of adjacent pieces is positioned on the Different Plane, rather than same pieces have the stairstepping acting surface.Thereby it is semicircular two adjacent pieces 28,29 that Fig. 5 a illustrates its cross section, and the bristle of pieces 28 is longer than pieces 29.In Fig. 5 b illustrated embodiment, the mutually different circular cross section pieces of three beams length is arranged in layout shown in Figure 7, the bristle of pieces 30 is the longest, and pieces 31 is middle long brush hairs, and the bristle of pieces 32 is the shortest.

Shown in Fig. 6 a, another kind of design is shown, wherein, the diameter of adjacent pieces 33,34 and 35 bristle is different, or shown in Fig. 6 b, the bristle of adjacent pieces 36,37 has different qualities, for example makes with different materials or has different surfaces characteristic.
